Meaning and Definition
An instrument for measuring atmospheric humidity, consisting of two thermometers, one with a dry bulb and one with a wet bulb.
A device, often whirled manually (as a sling psychrometer) or used in an aspirated housing, that determines relative humidity or dew point by comparing the temperatures of the dry and wet bulbs. It is a fundamental tool in meteorology, HVAC, and various industrial processes.

Common Mistakes When Using “psychrometer”
- Misspelling: 'psychrometer' (correct) vs. 'phycrometer' or 'psycrometer'.

FAQ
Frequently Asked Questions
A psychrometer is a specific type of hygrometer. All psychrometers are hygrometers, but not all hygrometers (e.g., capacitive or resistive electronic sensors) are psychrometers.
The water evaporating from the cloth wick around the wet bulb absorbs latent heat from the thermometer bulb, causing its temperature to drop. The rate of evaporation (and thus cooling) depends on the air's humidity.
Meteorologists, HVAC/R technicians, agricultural scientists, archivists/museum conservators, and industrial process engineers commonly use psychrometers.
It is a classic, manual type of psychrometer where the two thermometers are mounted on a frame attached to a handle. The user whirls (slings) it in the air for a minute to ensure adequate airflow over the bulbs before taking a reading.
An instrument for measuring atmospheric humidity, consisting of two thermometers, one with a dry bulb and one with a wet bulb.
Psychrometer is usually technical in register.
Psychrometer: in British English it is pronounced /saɪˈkrɒm.ɪ.tər/, and in American English it is pronounced /saɪˈkrɑː.mə.t̬ɚ/. Tap the audio buttons above to hear it.

Learning
Memory Aids
Mnemonic
Think of 'psychro-' meaning 'cold' (like in 'psychrophile', cold-loving organism) and '-meter' meaning 'measure'. It measures the 'coldness' caused by evaporation (wet bulb), which relates to humidity.
Conceptual Metaphor
A TALE OF TWO TEMPERATURES: The instrument tells a story where the difference between two siblings (the dry and wet bulbs) reveals the invisible character of the air (its humidity).
